The Goodman 10716003 Natural Gas Burner Orifice is a genuine OEM replacement (also called a gas spud) for the GMV90703BXBA gas furnace. Each orifice is precision-drilled to a specific diameter that meters the exact volume of natural gas into the burner for clean, efficient combustion at the furnace's rated BTU input. A worn, corroded, or incorrectly sized orifice causes poor flame, sooting, or reduced heat output.
Orifice sizing is critical to safe combustion. Genuine OEM orifices are drilled to Goodman's certified specification for this model. Generic orifices may vary in bore diameter, causing over- or under-firing. Always match the OEM part number for correct gas metering and safe operation.
Moderate (2/5). Requires shutting off gas and power, removing the burner assembly, and unthreading the orifice from the manifold with a socket. Recommended for those comfortable working on gas appliances; verify orifice count matches your burner set.
